CHARLES L. KELLER, or WYOMING, onrof ROOFING.

Specification of Letters Patent.

Patented Aug. 3, 1929.

Application filed September 22, 1919. serial No. 325,340.

To all whom it may concern:

Be it known that I, CHARLES L. KELLER, a citizen of the United States,and a resident of Wyomin in the county of Hamilton and State of @hio,have invented certain new and useful Improvements in Roofing, of whichthe followin is a full, clear, and ex act description, re erence beinghad to the accompanying drawings, forming part of this specification.

My invention relates to roofing materials made up from compositionmaterial such as a fibrous body with a slate surfaced waterproof asphaltcoating or of'equivalent composition roofin In the use 0% such materiala well developed art has sprung up in recent years, both in the use ofindividual shingles or tiles made up of composition, and in the use ofstrips of material cut out and laid so as to giv; a shingled or tiledappearance to the roo My invention involves among other things a methodof centrally cutting, or cutting between the edges of a strip of suchmaterial whereby no loss of the material is involved, and stripsprovided thereby, which may be employed so as to give a wide ran e ofeffects, while still providing a watertlght and weatherproof roof. Italso involves a new form of tile and roof provided thereby, and a newmethod of cutting out the separate pieces from a long strip of preparedmaterial, whereby the laying of the pieces can be done in a wide rangeof manner, and without leakage at any joints.

In addition to these advantages I am enabled to expose a greaterpercentage of the strip when laid on the roof, and thereby work out moreeconomical use of the material. In other words, not only the tabs butalso greater parts of the body are exposed than is the case of any stripshingle within my knowledge hitherto produced.

Besides this advantage, I am also able to break up the monotony of thepresent styles of shingles by achieving the effect of large and smallslabs, and slabs of different shapes which has never been attempted withstrip shingles before, to my knowledge. In other words, by using mystrips and varying the method oi laying, I am able to produce roots ofvaried efi'ects.

In these oft-acts I prefer that two edges of extensions or depressionsalways to-= gether, raising the roof at these points in a waIy' neverobtainable with other strips.

accomplish the above noted features with their attendant advantages aswill be hereinafter more specifically pointed out and claimed.

In the drawings,

Figure 1 shows a preferred form of centrally cutting a piece of roofingmaterial.

ig. 2 is a view of a roof construction made up of strips taken from theone side on? of the cutting shown in -1.

ig. 3 is a view of a roof made only from the other side of the cuttingof Fig. 1.

Fig. 4 is a view of a roof made from "m alternating courses of bothrights and lefts from Fig. 1. v

Fig. 5 is a view showing an" individual normally laid shin le effectmade up by Jay ing staggered over ying courses of the strip shown andused in Fig. 5. I

Fig. 6 is a view showing the basic T shaped unit of m invention.

As shown in ig. 1, a piece of composition roofing material 1 is employedand a zig zag cut made lengthwise of it to form alternate extensions 2,2, for the right half A, and 3, 3, for the left half B. The extensionsand the alternate depressions be tween them for each half are of uricual size although rectangular in shape, an it is readily to be observedthat the extensions of one half form the depressions in the other.

One difiiculty in laying a roof from a tile of this character is thatthe long pieces of material cannot be used due to their bulk, and theymust be'separated laterally into sections. To do this, a wide spaceortile effect shingle is subject to the danger of exposing the line ofjointure between two adjacent pieces in a single course, by the spacingof the shingle ike extensionsof the next course.

I avoid this danger, however, by cutting the halves of the long strip atdifferent points considering'the original full width piece as a whole,always making a cut which will divide one of the half strips between thesides of a depression. Thus I make the staggered cuts and 5 in the fullwidth strip 1, thereby bisecting the depression points of the rights andlefts. I may maize whatever length that is desired. every strip,however, b essentially a number bugs. as one of unseparated T-shapedunits, as appears in Fig. (i.

It is not. necessary that but two extensions, or, as I will term them,shingle portions, to each unit be provided as shown in the drawor moreunits may be employed. The essential point is the-cross cutting of thecontinuous body of the strip on a line which intersects the depression,or space between shingle portion extensions.

In laying the root. it the cut is made halfway between shingle portions,the result will be that all pieces of each course are made up of equal Tshaped units and the pieces may be laid with the extensions of onecourse abutting against the edges of the depressions of the precedingcourse. This will bring the lines of division of each course beneath theextensions of the succeeding course, and thereby protect the roofagainst leakage.

For this purpose. ordinarily a double cutter will be necessary that willmake two cuts and 5 on different lines, as this will be easier thancutting the strips after they have been separated into halves, andprevent cutting either shingle through a projection. Double cutters havelong been used in the art of paper making where sheets of paper are cutto different lengths, but this, I believe, is the first instance of itsapplication to cutting strip shingles.

It will be remembered that the rights and lefts of the cut strip are notthe same and in .view of this either of all letts, all rights, oralternate lefts and rights, may be laid in courses or further tiled ormosaic efi'ects gained by distributing the rights and lefts in layingthe roof. The cross cuts 4 andv 5, must, however, be made between thesides of extensions so as to provide for the overlying feature hithertopointed out, which is possible as a continuous process only with adouble knife cutter.

Fig. 2 shows a roof made up of courses made up from the rights of Fig.1, in which the extensions are of less size than the depressions. Thisgives a novel T-shaped effeet, which is very pleasing if laid with theextensions of one course laid to abut centrally on the base line of thewide depressions of the preceding course.

Fi 3 shows a roof made up of the lefts of Fig. 1. in which theextensions 2 of each course centrally overlie the narrower de- 1pressions of the preceding course.

Fig. 4 shows a roof of a very novel paneled effect made up of alternaterights and lefts, with the extensions 3 of the lefts all in linevertically, and the extensions 2 of the rights all in line vertically.

Here again the cross cuts 4 are always located beneath an extendingportion of the next course, and the effect given is of continuousstaggered rows of wide and narrow panels running vertically of the roof,as distinguished from running laterally.

By the mention of these three forms of roof made 11 1 from the stripsprovided by my cutting, do not wish to limit myself to them alone, sincethere is a wide range of design which it is possible to obtain, bearingin mind that the depressions and extensions must be of relativelydifferent size, and the cross cuts must be between extensions orpreferably should exactly bisect the body portions between the sidewalls of the depressed portions.

I may further form my zig zag cut so that the shingle extensions andspaces vary for the individual sections in width and depth. There willbe matching rights and lofts produced by such a cut but the shingleextensions will not be uniform for single courses.

A further arrangement of the type of strip shown as the right hand stripA in Fig. 1 may be made which will approximate the appearance of anindividual standard shingle roof, as customarily laid.

As shown in Fig. 5, the courses may, in one form which I have employed,be made of strips having a five-inch body portion, four-inch extensions,said extensions being six inches wide, and lying 'eight' inches apart,and this figure is drawn approximately to scale on such a basis. Thesecond course will be laid so that its extensions 3 lie between theextensions of the first course, in the particular dimensions selected.

The third course will be laid to bring its extensions into staggeredrelation with the first course, and so on. In a strip of the dimensionsabove mentioned, the cross out being as heretofore described, the exten'sions of the third course will abut on the line of divisions of thepieces making up the second course.

The strips having a five-inch body, as compared to a four-inchextension, the re sult will be that the first course underlies theconnection joint of the pieces of the second course for a full fiveinches, whereas the exposure of the joint will extend only for fourinches. Thus the joints of the pieces in the various courses will bevery amlply protected.

laying of a root according to this last plan will result in a verystrong and lasting structure, while the appearance will be moreconservative than the other roofs which have been heretofore described.

In all types it can be observed that there is preferably a doublethickness of material throughout, and in the last one described (Fig.5), there is a triple thickness except for the spaces of one inch (seeselected dimensions) between the extensions of the overlying courses,which will be double.

It is not desired because of the details above set forth to limit myclaims that follow due to my failure in all or any instances to setforth alternative structure or methods of accomplishing them.

aving thus described my invention, what I claim as new and desire tosecure by Letters Patent, is: g

1. That method of cutting out strip shingles for use on a roof whichconsists in cutting a median line through a piece of roofing material,said line leaving alternate extensions from the material at each side ofthe cut, and in cross cutting the material into sections or units bystaggered lines interseating the spaces between extensions intermediatethe Walls of said extensions.

2. A strip shingle roof com rising strip shingle units having bodyportions and bottom edge extensions simulating shingles said extensionsbeing spaced apart to revea a substantial area of the sublying coursesas distinguished from being mere slots, the extensions and spaces beingof unequal width for each course, and the extensions and spaces for somecourses width from the spaces and extensions of other courses, but withthe total width of a space plus an extension being always equal foreachcourse.

3., A strip shinglin for roofs, comprising body portions having ottomedge extensions simulatingshingles, said extensions being spaced apartto expose portions of underlying strips of substantially shingle-likesize, as distinguished from a crack or meeting line between adjacentsurfaces, said body portions terminating in oppositely project ing endsfree of extensions to form said spaces between similar ends of ad o1n1ngstrips in a course.
